Services include:

Computed Tomography

A computed tomography , also known as a C.T. scan or a CAT scan, creates a series of images that reveal conditions not detectable with conventional X-rays. A beam of radiation is set on the studied patient and moves around the body, creating multiple cross sectional images. The patients must lie still to ensure the accuracy of the study.  C.T. scans are performed by Medical Radiation Technologists who have specific training in C.T. scanning.
